laptop battery weirdness
I haven't used my old Toshiba laptop in a couple of weeks but dusted it off last night. There were several Win10 updates needed so I let them go ahead. A little later I noticed my battery (a larger capacity unit) was at 100% charge and I disconnected the charger and, immediately, the laptop died.
It wouldn't power up again unless it was back on the charger but then indicated full charge. I suspected the updates and spent a while rolling them all back to no avail. I dug out an old battery, charged it and the laptop ran fine on battery power. I have a fully charged laptop battery (apparently) that the laptop no longer accepts. Weird.

Re: laptop battery weirdness
Battery is goosed I suspect. Had the same, in a couple of laptops now. I surmised it's along the lines of the mains power isn't being bled off into the battery as it can't hold charge. Whatever it is in the laptop that monitors charge is just seeing that the battery isn't taking any so must be full.

Re: laptop battery weirdness
I had an Asus which did a similar thing, battery said full but it held almost nothing. Having read up on the problem it appeared that simply disconnecting/removing the battery for 30mins or so might solve it, and in this case it did.

Re: laptop battery weirdness
get a 12v bulb with some wires and crocodile clips and connect to the battery + and - this should discharge the battery. once the battery is empty plug back into laptop and charge. if that dont work then battery is fubar.
